HARVESTER-REEL.

To all whom it may concern;

Be it known that I, FRANCIS M. BAKER, a citizen of the United States,resident of Viroqua, in the county of Vernon and State of \Visconsin,have made a certain new and useful Invention in Harvester-Reels, anddeclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the invention, reference being had to theaccompanying drawings, and to letters 6r figures of reference markedthereon, which form a part of this specification.

Figure l is an end view of the invention as applied, with the reel batsloose and free to swing upon their pivots to drop into the grain. Fig. 2is a side view of the same, partly in section. Fig. 3 is a longitudinalsection of a reel arm, showing the hinge attachment, and the bat free toswing. Fig. 4: is a face view of a reel arm having the hinge attachment.Fig. 5 is a similar view from the opposite face. Fig. 6 is a side viewof a reel arm showing the hinge attachment, and the bat fixed to preventits swinging upon its pivot.

The object of the invention is to provide an improved harvester reel,whereby it is designed to save time and expense in repair and preventwaste of grain; and the invention consists in the novel construction andcombinations of parts to this end, as hereinafter set forth.

In the ordinary reel the bats or slats are attached to the reel arms ina manner which, although strong enough, is not designed for operation ina very delicate manner, or in such way as would seem suitable in workingamong the heads of ripe grain.

In the accompanying drawings it is designed to illustrate myimprovements,whereby the hat 1 is connected to the reel arm by a slendermetallic extension or stem, which is secured to the reel arm by anattachment plate. These extensions are designed to be connected to theattachment plates by spring hinges, and to the bat by a link connection,whereby the bat is designed to have free movement of gravitation.

The numeral 2 indicates the reel shaft and 8 the ordinary arms extendingtherefrom.

4 is an attachment plate secured to the end of the arm at 5, and to theend of this plate which projects beyond the end of the arm is bolted theinner member 6 of a hinge Specification of Letters Patent.

plate, having lateral ears 7 to which are connected by a pivot bolt 8the lateral branches 9 of the end of a slender extension or stem 10,which forms the outer member of the hinge and is several inches inlength. The inner hinge member 6 is provided with a stop flange 12 whichprojects over and engages a bearing 22 of the branched end of the stem10 when the extension is in the plane of the arm 3 of the reel. A spring13 is provided in connection with the hinge, to hold the arm andextension in the same plane with sufficient rigidity to provide forefficient work on the grain. The

hinge port-ion has a box-like form, closed in front by the hinge plateand its stop extension or flange and at the sides by the branches andcars, so that in its forward working motion it is closed and protectedagainst the entry of matter which might clog the working, as it isdesigned that this spring shall yield in the case of some undueobstruction in the path of the bat, in order to avoid injuring theparts. The leverage of the extension forming the inner member of thehinge is designed to facilitate this action, and at the same time itsslender character prevents undue contact with the grain. The ends of thebat extended beyond the reel arms are strengthened by the extensions,which in this position have an outward inclined portion 21, designed toprovide for its connection to the bat at the extremity of the latter.These thin extension stems are designed to interfere as littlev aspossible with the impact of the bat in its work.

The end of the extension is designed to be curved toward the front asindicated at 14, and the end of the curvature is flattened andperforated in eye form as at 15, to receive the hook end 16, of a shorthook bolt 17, designed to pass through the upper portion of the bat, towhich it is secured by a nut 18. The hook bolt is provided on its underside with a shoulder 19, to engage the surface of the bat, and in rearthereof with a shoulder 20 to engage the hook end of the extension stem10. These shoulders are conveniently formed on the hook bolt as theopposite ends of a projection from its under side. lVhen the hook boltsare tightened up on the bat their inner shoulders engage its rearsurface and prevent the bolt from turning so as to throw the hooks outof posi tion. The outer or rear shoulders of the bolts abut against thehooks when the bat has descended to working position. But

while the reel arm is descending from vertical position into thegrainthe bat hangs freely from the hook ends in nearly vertical 5posit-ion, to enter the grain, and as the connection is of linkcharacter, play is pro-;

vided for, to avoid somewhat a rigid impact.

The reversal to horizontal position of the bat takes placeautomatically, through the action of gravlt-y, when the reel arm reachesits highest polnt 111 its revolution, and this reversal is in theopposite direction to the bend of the hinge at the other end of theextension stem. The link-like connection of the bat with the end eyes ofthe slender extensions is designed to provide for a very free movement,which is not liable to be clogged, and as the attachments are all nearconditions of the grain, the bat is held in I rigid relation to the stem10, by means of a removable angular notched brace 24, which is readilyattached to the bat by means of the hook bolt, in position to engage thestem by the notch 25, in the end of its angular arm.

A perforated washer 26 is usually pro 3 vided on the rear of the bar,between the same and the hook bolt, said bolt having an extension 27 atthe end of its hook for. engagement with a perforation or seat 281 ofthe washer, to keep the hook from turn- 1 ing and prevent undue wear.

Having described the invention, What I claim and desire to secure byLetters datent 1. In a harvester reel, radial arms extending outwardfrom the reel shaft, an at' tachment plate for the outer end of eacharm, an inner hlnge member carried by said plate and having a frontguard portion and rearward turned lugs, a branched outer; hinge memberhaving a central stem eXtension, a hinge bolt 'connectin'gthe branchesof the outer member and said lugs, saidi inner member having a stopextension of its front guard portlon engaging said stem, and l a springfor normally maintaining the engagement of stop extension and stem tokeep said stem and said plate attachment normally 1n ahnement.

2. In a harvester reel, radial arms extending outward from the reelshaft, an attacha reel bat, shouldered eye bolts carried by said bat andhaving each pivotal engagement with said eye, the shoulder of the eyebolt having stop engagement with said eye to limit the pivotal movementof the bat in one direction, and the edge of the bat having stopengagement with said stem to limit the movement of the bat in theopposite direction.

In a harvester reel, radial arms extending outward from the reel shaft,an attachment plate for the outer end of each arm, an inner hinge membercarried by said plate and having a front guard portion and rearwardturned lugs, a branched outer hinge member having a central stem, ahinge bolt connecting the branches of the outer member and said lugs,said inner member having a stop extension of its front guard portionengaging said stem, a spring for normally maintaining the engagement ofstop extension and stem, :1 forward bent outer portion of said stemprovided with a terminal eye, a reel bat, double shouldered eye boltscarried by said bat and having each normal pivotal engagement with saideye, an angle plate between one of the eye bolt shoulders and said bat,the other eye bolt shoulder having stop engagement with said eye, andthe angle plate having engagement with said stem to maintain the bat infull acting position.

In testimony whereof I aflix my signature in presence of two witnesses.
